Transmission Temperature

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

The IPC uses a base transmission temperature message then filters the transmission fluid temperature signal based on engine rpm and the length of time the engine has remained in the off state to provide a more accurate gauge indication.

The IPC receives the transmission fluid temperature data, the engine rpm data and the engine off status messages from the GWM over the HS-CAN3. The GWM receives the transmission fluid temperature data, the engine rpm data and the engine off status messages from the PCM (gas engine) or TCM (diesel engine) over the HS-CAN1.

The IPC receives the transmission fluid temperature message from the GWM over the HS-CAN3. The GWM receives the transmission fluid temperature message from the PCM (gas engine) or TCM (diesel engine) over the HS-CAN1. The PCM (gas engine) or TCM (diesel engine) filters the transmission fluid temperature signal to remove fluctuations that could affect the stability of the transmission temperature gauge indication.
